IMPORTANT: Before entering programming mode, have in possession all of the transmitters you will be using on the vehicle. Once you program the transmitter, all previous codes will be erased from the memory. The other transmitters will not be functional until you program the transmitters again.

Insert key into ignition and remove it from the ignition key cylinder at least six times

procedure is performed too fast, system will not enter programming mode.

Within 5 seconds, push ANY button on the remote transmitter. Your Hazard Lamps should
flash. NOTE: Do not press the button more than one time in the above step. If the button
is pressed more than one time, the programming procedure will not be successful.

If there are any remaining transmitters (including the old ones), unlock then lock all doors
using the driver’s side power lock/unlock switch and within 5 seconds, push ANY button
on the next remote. Your Hazard Lamps should flash. Repeat this step for each
transmitter (including any existing transmitters).

Turn the key to the OFF position, remove keys from the ignition,
